In 1860 a manual vacuum cleaner was invented by Daniel Hess of West Union, Iowa. Called a 'carpet sweeper', It gathered dust with a rotating brush and had a bellows for generating suction. Another early model (1869) was the "Whirlwind", invented in Chicago in 1868 by Ives W. McGaffey.
The vacuum cleaner uses an electric motor that spins a fan, sucking in air – and any small particles caught up in it – and pushing it out the other side, into a bag or a canister, to create the negative pressure.A vacuum cleaner is one of the most essential home appliances one can have forcleaning/sanitizing one's home. It works on the principle of flow of air from area of high pressure to area of low pressure. An electric motor is attached to a fan that spins it at high velocities.
Canister vacuum cleaner for home use
A vacuum cleaner, also known simply as a vacuum, is a device that causes suction in order to remove debris from floors, upholstery, draperies and other surfaces. It is generally electrically driven.
The dirt is collected by either a dustbag or a cyclone for later disposal. Vacuum cleaners, which are used in homes as well as in industry, exist in a variety of sizes and models—small battery-powered hand-held devices, wheeled canister models for home use, domestic central vacuum cleaners, huge stationary industrial appliances that can handle several hundred litres of dust before being emptied, and self-propelled vacuum trucks for recovery of large spills or removal of contaminated soil. Specialized shop vacuums can be used to suck up both dust and liquids.
